To all whom at may concern:

Beit known that I, HENRY F. MEGILL, 'of the city of Brooklyn, county ofKings, and

State of New York, have invented certain new and useful Improvements inFulminating or Percussion Strips; and 1 do hereby declare that thefollowing is a specification thereof, refer.

ence being had to the accompanying drawings.

My invention relates to improvements upon the well-knownpercussion-strips which have pellets of fulminating compound depositedat regular intervals along and throughout their entire length, which areusually made about two feet long and rolled up in a round coil, and inthis form applied to use in various kinds of devices for lightingpurposes.

Figure 1 is a perspective view of my improved percussion-strip rolled upinto a coil with the fastening end projecting therefrom. Fig. 2represents a side elevation of the machine to which my improvementsapply, and which contains my percussion-strip coiled up in the usual wayand attached to the windingwheel according to lny improved plan. Figs.8, 4, and are perspective views of my improved percussion-strips laidflat to show the differential manner of placing the pellets. Fig. 6 is aplan view of the same before they are cut from the sheet.

The object of my invention is' to provide percussion-strips with cheap,reliable, and simple means by which they may be securely, buttemporarily, attached to 'a certain recently-patented feeding device inautomatic lighters,. which is known as the wimiing\vheel."

It also has for its object the proper regulation of the pellets withinsaid strips whereby they may be fed successively to an( simultaneouslywith the falling` of the hammer of the machine by said winding-wheel.

My invention therefore consists in provid in g said percussion-stripswith suitable heads or flanges by which' they may be fastened be tweenany twoof the projections of said winding-whee the said projectionsservingaslugs to take hold of the said heads or flanges and `prevent theends of the strips from drawing through when the strain or draft isapplied to them by the turning of seid wheel to wind the strips up.These percussion stri s are disposed of, and fresh ones repl one afteranother, and by this means of fastening the changes are readily andquickly made, which saves considerable trouble to the consumer in usingthe machine.

Heretofore the percussion strips were se cured to the winding-wheel bylooping the blank or loose end around one of the projections on saidwheel, which is slow and obje-ctionable,whil myinvention provides acheap ready-made attachment. 5

My invention also consists in placing oi depositing the pelletsofffulminate within said strips d'erentially, or at increased distancesapart throughout its length.-

It is understood that as the strip is wound around said wheel each layerwill increase its travel in accordance with the .increase ot' itsdiameter; and as the hammer does not alter its number of strokes duringany of the successive revolutions, the pellets, if placed at regulardistances or intervals apart, will eventually arrive at the hammerofteuer than the hammer will fall, and many will bc wasted thereby; butif the stripsare made according to myimproved plan-say, starting thepellets oneeighth of an inch apart and gradually increasing tothree-eighths, or whatever degree is required by the size of thewheel-each pellet will be fed regularly to the hammer and be explodedsingly.

In the drawings, A represents my improved percussion-strips. The mannerof placing the pellets between two layers of paper, one thick and theother thin, closely pasted together tO prevent the explosion of one ofthe pellets from communicating with the other, is as has been doneheretofore, and a represents the thin'tissue layer, and b tlie thickerlayer. In accordance with my invention, however, these pellets offulminate are deposited dierentially, beginning at the end to beattached tO the wheel, and increasing the space between them toward theother end, as shown in Figs. 3, 4, and 5 by letters c.

B is the loose or projecting end of the percussion stri A, which islapped over and around a p f, and gulnmed or pasted snugly and firmlytogether to form a stud or head, C, or the flanges d d, on cach side ofsaid strip.

The strips are attached to the windin g-wheel, as shown in Fig. 2, bypassing the end of the strip edgewise between the projections n, withthe stud or heed O within the circuit of said BEST AVAiLABLE COPY a tl 5material. Iprefer, however, to make said pads sired, within the end ofthe of twine or strips of card-board and while the percussion-'stripsare .in the (uli sheet drawer ay the' across the ends from one side ofthe sheet to the other.

said twine or card-board and fold and secure, as above described, andthen cnt the percussion-strips from the sheet in-f-he usual manner, asshown by dotted lines in Fig. The said pad maybesecured, if deonstrips,by layin and pastin it between th'e two layers a au b, and lapp ug orfolding the end of one lig'ier over the other,.ss shown by Fig. 1.

In 5 the pad is represented as being made o twine, while in the otheriignres of cani-board.

I do not claim ns mg.' invention the percussion-strip in itself, for iknow that :trips of fulmimitng or igniting pellets have heretoforeexisted; but I make certain valuable improvemente on said percussion or'igniting. strips. Neither do I wish my claims to be construed .to coveror include strips of any other kind than those which are provided withfulminating or igniting compound which are ada ted 3o to automaticlighting devices; nor do I aim the winding-wheel or its projections.

,1. .at the end withs stud, knob, or hea Idem mim the umida bearings,the tension-spring; or any other part of the machine shown Fig. of thedrawings, the said l machine bein shown simply to illustrate the mannerin w iehmy improved percussionstri area piled.

provided which atl is- A percussion or igniting stri itm beheld b the inor project ons on the nding-wheyel of angutomatic lighting `device.substantially as h erein set forth and deecribed.-

2. A percussion or iguiting strip provided with a suitable iiange oriiangrs, d d, for .securing the end of said strips between the lugs orpro ections on the winding-wheel ci' an automa o lighting device,substantially as described.

3. A mision-strip provided with peilen of faim natiu or igniting.compound placed dioreutially rcughout itslength for regnlat ing their,supply to the hammer-head when o by a uding-wheel of un automaticlighting device, substantially as described.'
